The usual latch ring l2 is positionedover thetop of lthe needlev cylinder and is pivotally connected as by arms Islto some stationary part of the machine frame as indicated at I6 in Fig.2. Said latch lring is provided with the usual gap I8 l for thereceptionlof theyarn guide iingers I9 (indicated generally in Fig. 2) and withthe conventional anged guard ring which is.r otataf bly mounted forselectively opening and closing i said gap. The shear plate 22 carries`the usual yarn cutter and clamp v24 and pivoted yarn clamp 26 providedwith aleaf spring 28 as shown in Figs. '1, 2, and 10. Said shear plate,is supported in fixed position 'in relation 'to latch ringy l2 by a lrod 30 secured at its lower end to said shear plate and adjustably iixedas by a set screw l2 in a hub 38 ary sleeve 38 carried `by' saidbracket.

' stationary sleeve 52. Said tube is provided at its -the guard ringforopening and closing the particular reference to Figs. 1 and 3 of thedraw- 458 vis driven from shaft 40 by gears 80 and 82. As here shown,the clocking mechanism Gear 80 is fastened to the upper end of shaft 40comprises a tube 50 joumalled for rotation in a by a sleeve 54 integralwith or otherwise fixed to said gear. Intermediate gear .82 transmitsthe lower end with a plurality of, here shown as two, motion of gear 80to gear 58 and is mounted for yarn guiding fingers constituted by narrowtubes through which the yarn passes outwardly from the interior of tube50. Said yarn guiding fingers are 'positioned for rotation close to theinner periphery of latch ring |12 for feeding yarn to the rotation onplate 10 about the shank of a pivot screw 85 whichholds said gearremovable in position on said plate and in mesh with gear 58.

In accordance with the present invention, provision is made for raisingthe yarn fingers 54 upneedles N when the latterr are raised for thiswardly 4away from the needles automatically purpose, it being understoodthat the pattern of when the needles are raised for knitting the heelthe clocks or other design elements formed by and toe portions of thestocking, such raising of the yarn suppliedby ngers 54 will depend uponneedles taking place in the Scott 8: Williams the needles raised inposition to receive said yarn, the raising of appropriateneedles beingaccomplished by any suitable mechanismas that pro= knitting machine withwhich the clocking or patterning attachment of the present invention isembodied as illustrated herein. .Provision is also vided heretofore incircular knitting machines vof made for interrupting the rotation of thebobbin the type described herein. Yarn lingers 54 have standard of yarnfingers 54 in the raised position a circular'path which extends intogroove 55 of of the latter. In order to 'permit said yarn finthe latchring. Said groove receives and guides gers to be raised tube 50 ismounted for longitudinal movement in sleeve`52 and ring 14 on gap |8and'is itself conventionally provided with plate 10. A spring 88 bearsat one end on the a gap 59-through which fingers 54 can move into lowerenlarged portion 90 of tube 50 and at its groove 55. When the gap 59 inring 20 is thus other endY on the end 92 of sleeve 5,2, andtherepositioned' to permit entry of fingers 54 into fore resilientlyopposes. upward -movement of groove 55, the ring is positioned foropening gap tube 50 and yarn fingers 54 carried thereby. It |8. When thering 20 is positioned to close gap will be understood that when tube 50is moved to I8, the gap in the ring is out of registry with fingers 54and the latter are prevented, by theV portion ofthe ring adjacent itsgap, from .entering groove 55, but at that time the ngers are inretracted stationary position as will hereinafter be explained. Thus,yarn fingers 54 are rotated adjacent the needle circle. Said fingers 54rotate at such'ispeed in relation to the needles N that yone of saidyarn fingers supplies yarn to theA needles for forming the clocks at oneside of the stocking while the other of said yarn fingers supplies yarnfor forming the clocks at the opposite side of the stocking, whereby theclocks at one side of the stocking are independent of the clocks at theother side of the stocking thereby eliminating connecting or. iioatingthread por.- tions extending from one line of clocks at one side .of thestocking to the line of clocks at the other side of the. stocking whichin certain maf chines of the prior art were unknit and wre required tobe eut from the stocking as hereinbefore explained. On'the other handthe clocks thus knit into the stocking .are firmly retained therein andloose ends of yarn or threads are eliminated.

raise the yarn fingers 54 above the needles when the latter areoperative to knit the heel and toe portions of the stocking, bobbinstand plate 55 is raised, and clutch elements 50 and 52 are therebyautomatically disengaged for interrupting the driving connection betweensaid elements. For more quickly arresting the motion or tube 50 and ofthe bobbin stand when the latter is disengaged from its drivingconnection, there is provided a brake member`94 provided with a frictionshoe 55 which is in engagement with tube 50 within sleeve 52. Said brake94 is positioned within tubular extension 95 of sleeve 52. Anadfiustable screw 99 is threaded into the outer end of tubularextension98 for adiusting the friction of the brake on tube 50. It will beunderstood that the friction of said shoe 95 is insumcient to impede therotation of said' tube when the -latter is driven, but in view of thelight weight of said tube and associated parts said friction shoe. iseffective to quickly stop the rotation of said tube and of the bobbinstand when the driving connection of the stand is disengaged.

The means for automatically raising bobbin standplate 55 comprises aroller |00 carried at one ed of a lever |02 which is pivotedintermediate its ends on a pivot screw |04 secured to a Tube 50 is fixedto and depends from the bobbin bracket extension plate |05. Outer .endof pivstand plate 55, centrally thereof, by means of a ,Y Oted lever |02is prvidedwith a fixed upwardly sleeve 51 fastened to said `-plate andto said extending arm |08. Lever |02 is operated by tube. 'I'here is areleasable driving connection bea pivoted lever I0 connected by a link`||2 to the tween plate `55 and a gear 58 constituted by a proupper endof arm |08. Lever ||0 is pivoted injection' 50 depending from the lowersurface of termedatc itscndaas at H4. to some stationary plate 55for'engagement by a projection 52 xed, part of the knitting machine inposition to be ento a plate 54 fastened as by a set lscrew 55 to gagedat its lower end ||5 by a cam on the main A gear 58. Gear 58 rests on ashelf 'l0 fixedto of gear 58 and annular plate 54 is prevented by tingthe stocking thereby to project andretractav retaining washer18 whichoverlies the inner top marginal edge portion of the\ top of gear 58within annular plate 54. Retaining washer'18 isv .xed by pin 15. It willbe observed that projection-\50 on plate '.55 and projection 52 on plate54 drum |20 of the machine. It will be understood that lever ||0 iscontrolled by drum |20 forlowering and raising bobbin stand plate 55 andtube 50 at the appropriate times in the course of knityarn fingers 54,said yarn fingers effective or ineffective to supply yarn to theneedles, as may be necessary in the course of theV automatic operationof the machine for making a stocking.

' AS shown more clearly in Figs. 1 and 6, there is provided a cilrvedyarn guard bar 22 disposed inthe latch ring between the inner peripheryof the latter and the outer edge of shear plate 22, for preventing theneedles from tangling with the vyarn supplied to the knit web-byyarn'ingers 54. Guard bar |22 is fixed to a part |24 of the bracket 34by a vertically extending bar portion |26 fastened to said bracket part|24 in any suitable way as by screws |28 (Fig. 7). There is alsoprovided a yarn guard pin |34 positioned between barV 22 and the edge ofplate 22, for guiding the yarn fed by fingers 54 'and attached tol theweb below the shear' plate-22, said yarn 'engaging pin |34 betweenl saidpin and guard bar |22. Provision is made for retracting pin |34 when`yarn ngers 54 are raised to retracted position. For

this purpose pin |34 is formed as part of an Lv shaped member |36pivoted at its end |38 remote from the yarn-engaginz end of said`guardpin on a bracket extension plate |40,by means of a pivot screw |42 (Fig.1). Member |36 is connected to leyer |02 by means of an adjustablesectional link |44 comprising apart |46 pivotally 'connected at itslower end" to ,memberl |36 and a part |48 the yarn supplied by saidfingers and connected iso ' to the knit web; passes over plate 22, asthe needle cylinder rotates, and is engaged by spring 28 of clamp 26 andcut from the web by cutter '24.

' As shown in Figs. 10 'and 11, plate 22 has a bevelled edge portion |53for guiding the yarn into engagement with said clamps and cutter.,/Referring now to the bobbin stand vhereinbefore mentioned inconnection with plate 56 thereof, it will be observed that the yarnbobbins B are carried by plate 56, being removably secured for rotationthereby on pins |54 fixed to and upstanding from said plate. Suitableyarn tension'- ing and take-up means for the yarn from each of saidbobbins supplied to the yarn fingers 54 are provided on plate 56. Ashere shown', there are two vertically disposed rods |56, each providedwith a lower foot portion |50 for securement to the upper surface ofplate 56, screws |60 beng provided for this purpose. A yarn guide hook|62 is removably secured by said screw |60 to the foot portion |58 ofeach rod |56. Each rod |56/ is provided with slot |64extendinglongitudinally of saidrod for the major portion. of its lengthand transversely of said rod for the full width thereof. A yarn take-upsleeve |66'provided with a transverse aperture |68 is movablelongitudinally downward movement of sleeve |66 and resiliently urgessleeve 66 toward the top of the rod.- A

yarn tensioni g device |12jis removably secured to the top of each rod|56 by aset screw |14'. It will be runderstood that the yarn Y as itleaves its bobbin is engaged by the spring-pressed plateA |16 of itscompanion-tensioning device' |12 and passes through an opening |16 (Fig.9) in block to rod |56.

- guide hook |62 on its companion rod- |56, and then it extends upwardlyand passes through the aperture |68 in sleeve |66 and through the slot|64 in rod |56 frein one side of saidrod to the other end, and n'allythe yarn extends downwardly-into one of the openings |82 in disc |84,

dles from the side of .cylinder at which yarn l0 fingers 54 arelocated.and to which 'yarn is supplied to said needles by said iinger to adiametrically opposed point in theV circular path of the needles. Duringapproximately the other half of the revolution of the needle cylindertake-up sleeves |66 move upwardly thereby taking up the slack in theyarn. It will be understood that as the yarns supplied by the needles 54are knit P/ into the web the tension of the spring on the take-upsleeves increases sufficiently thereby to tensionthe yarn forwithdrawing` the necessary amount of yarn from the bobbins through thecompanion tensioning device` |12. f

Thus it is seen that the constructions herein shown or described arewell adapted to accomplish the several objects of the presentinvention..

It will be understood, however, that the invention i may be embodiedotherwise than as here shown and that in the forms of the inventionherein disclosed, certain changes in the construction and arrangement ofparts may be made and will read` ily occur to lskilled artisans,particularly in View of the presentdisclosure'. Therefore I do not wishto be limited precisely to',the construction herein shown or described,except as may be required withn the scopev of the appended claims.
